Top complaints
Kyota Kiyomi M698 4D
- Pricey
Good Housekeeping's only con is that it's pricey compared with the other models on its list.
Source: Good Housekeeping
MassaMax MT339 4D
- Cramped for taller users
Although rated for 6'1" and 300 lb, a 5'10" Wirecutter tester felt the torso wasn't high enough, and the body scan set a 5'9" tester's shoulders 'at a weird position,' so programs missed their targets.
Source: Wirecutter - Weak heat
Most Wirecutter testers found the heat unsatisfactory, and three said it 'should have been warmer.' Amazon's summary says some owners find the heat isn't noticeable.
- Overly intense or faulty for some
Amazon's summary says some owners find it very intense on the lower back and functionality gets mixed reviews. A 1-star reviewer says that after about two and a half months it made an odd sound and some rollers hit painfully hard, with no support.
